AccountEdge and 64-Bit
Updated: June 3th, 2019
Apple announced today that a developer beta version of their new 64-bit macOS Catalina is available to registered developers, with a possible release in the fall. Apple plans to make a public beta available later in the summer.
As noted by macosrumors.com: “As with all new betas, you're not going to want to install macOS Catalina on a primary machine as it is early release software and could have major bugs.”
Please be aware that this new version of the operating system only supports 64-bit applications, and that AccountEdge is currently a 32-bit application. Therefore, AccountEdge will not work on Apple’s 64-bit macOS.
Again, if you install the beta version of the new macOS 10.15, AccountEdge will not be able to run. If you’re intending to run AccountEdge on your Mac, do not install the public or developer preview/betas of the new 64-bit operating system.
We are working towards a new 64-bit upgrade to AccountEdge, and we hope to release in a timely fashion to Apple’s actual release of their operating system. You will receive upgrade notifications. Until then, this is to serve as notification that AccountEdge 2019 and earlier will not work on Apple’s 64-bit macOS.
When running AccountEdge on High Sierra, MacOS 10.13 (or later) you may see a message about AccountEdge not being optimized for your Mac because it's a 32 bit application. As Apple says in the article linked to the message "Yes, you may continue to use 32-bit apps with your Mac today. Using 32-bit software has no adverse effects on your data or your computer.”
While AccountEdge is currently a 32 bit application, we have been hard at work on a 64-bit version.
Apple announced that the next MacOS version (suspected launch date in 2019) will be 64-bit only. We fully expect AccountEdge to be compliant with all future MacOS releases and to be 64-bit in alignment with Apple’s timeline.
As with any new operating system, we recommend you don’t install the next version of MacOS until it is officially released (in other words, don't run beta versions/public preview releases) if AccountEdge is critical to your business. We will share our compatibility statement when we have fully tested AccountEdge against the new, production version of the OS.
